Is there a way I can upload .psd's and .png's and pdf's etc... to my file manager? Every time I try to I get a error?

I already have the following in my site.php config file.

<?php define('UPLOAD_FILE_EXTENSIONS_ALLOWED',
'*.flv;*.jpg;*.gif;*.jpeg;*.docx;*.xla;*.png;*.swf;
*.doc;*.xls;*.csv;*.pdf;*.tiff;*.rtf;*.m4a;*.mov;
*.wmv;*.mpeg;*.mpg;*.wmv;*.avi;*.mp4;*.mp3;*.psd;
*.qt'); ?>

Invalid form token. Please reload this form and submit again. is the error that I'm getting when I try to upload a .tiff file.

I've also tried to upload a php.ini file to the root of my site and in my "files" folder with the following in it...

upload_max_filesize 20M
post_max_size 20M

The File Manager will upload normal pictures just fine though.

Any Ideas?
